The first command you typed is also used to create an executable (by default
a.out), since you did not provide the -c (compile only) or -a (create a library)
flags.

Change the first command to :
ocamlc -o pascal -custom unix.cma pascal.ml -cclib -lunix 

to create the executable with the name 'pascal'.

You could also have compiled pascal.ml :
ocamlc -c pascal.ml  (creates pascal.cmo and pascal.cmi)

then you could have created an executable with the compiled file :
ocamlc -o pascal -custom unix.cma -cclib -lunix pascal.cmo
